Abstract: Decontamination is both an important means and a key link in nuclear and radiation emergency disposal and medical treatment. Whether the decontamination facilities can meet the technical requirements and the decontamination processes are standardized, is critical and necessary for preventing the spread of pollution and reducing the absorption of radionuclides. We mainly introduce the decontamination of body surface in nuclear and radiation emergencies, aiming to provide a certain reference for future emergencies.

Key words: Nuclear and radiation emergency, Decontamination, Operational intervention level(OIL)
